House of Saxe-Coburg and Gotha

The House of Saxe-Coburg and Gotha was a line of the House of Wettin that ruled the German state of Saxe-Coburg-Gotha in addition to the countries of Belgium, Bulgaria, Portugal, and the United Kingdom. The house originated with Ernest I of Saxe-Coburg and Gotha in 1826, and its descendants became kings and princes; in 1917, the British branch of the family changed its name to the House of Windsor.
